Using the Lenox 3009696L hole saw is easy. First, choose the right arbor for your job. You can use 2L, 6L Snap - Back, 2L, 3L, 6L, or 7L Standard arbors. Then, secure the hole saw to the arbor. When you're ready to cut, make sure your workpiece is firmly held. This hole saw can cut through many materials like stainless and mild steel, cast iron, and more. Just start the drill and let the bi - metal and toothed cutting edge do its job. For maintenance, after each use, clean the hole saw with a brush to remove debris. Store it in a dry place to prevent rust. Be careful when handling the cutting edge as it's sharp. If you notice the cutting performance dropping, it might be time to replace the hole saw.
